Carsten Holms CH GR3 is a braided packing, constructed from 100% Grafan yarns, to form a truly exceptional capabilities and performance, pure Expanded Graphite Packing.
Under compression in the gland, CH GR3 die-forms into packing rings like CH GR2, whilst offering the advantage of avoiding the need to laboriously wrap CH GR1 ribbon tape around value stems or the cost of an inventory of many sizes of individual CH GR2 die-formed rings.
CH GR3 can be merely cut to length and spiralled into the gland. There is no need for individual cut rings, as is the case with conventional braided packings. Grafan is self-lubricating and will not shrink nor harden nor dry out in use.
